Again rhythm more readily admits of rests [*](i.e. in the musical sense. ) although they are found in metre as well. Greater license is, however, admitted when the time is measured by the beat of the feet or fingers, [*](i.e. in musio. ) and the intervals are distinguished by certain symbols indicating the number of shorts contained within a given space: hence we speak of four or five time ( τετράσημοι, or πεντάσημοι ) and others longer still, the Greek σημεῖον indicating a single beat.

In prose the rhythm should be more definite and

obvious to all. Consequently, it depends on feet, by which I mean metrical feet, which occur in oratory to such an extent that we often let slip verses of every kind without being conscious of the fact, while everything written in prose can be shown by analysis to consist of short lines of verse of certain kinds or sections of the same.

For example, I have come across tiresome grammarians who attempted to force prose into definite metres, as though it were a species of lyric poetry. Cicero, [*]( See Or. xx. 67, sqq. ) indeed, frequently asserts that the whole art of prose-structure consists in rhythm and is consequently censured by some critics on the ground that he would fetter our style by the laws of rhythm.

For these numeri, as he himself expressly asserts, are identical with rhythm, and he is followed in this by Virgil, who writes,

  1. Numeros memini, si verba tenerem
Ecl. ix. 45. [*](I have the numbers, could I but find the words. In this case the nearest translation of numeri would be tune. But, strictly speaking, it refers to the rhythm of the tune. )
and Horace, who says,
  1. Numerisquefertur
  2. Lege solutis.
Odes. IV. ii. 11. [*](And sweeps along in numbers free from laws.)
